If the water flow down by a gradual natural channel, its potential energy is gradually converted into heat by fluid friction, according to an admirable discovery made by Mr Joule of Manchester above twelve years ago, which has led to the greatest reform that physical science has experienced since the days of Newton. From that discovery, it may be concluded with certainty that heat is not matter, but some kind of motion among the particles of matter; a conclusion established, it is true, by Sir Humphrey Davy and Count Rumford at the end of last century, but ignored by even the highest scientific men during a period of more than forty years.

Less than a century ago the laborer had no rights, little or no respect, and led a life which was socially submerged and barren.... American industry organized misery into sweatshops and proclaimed the right of capital to act without restraints and without conscience. The inspiring answer to this intolerable and dehumanizing existence was economic organization through trade unions. The worker became determined not to wait for charitable impulses to grow in his employer. He constructed the means by which fairer sharing of the fruits of his toil had to be given to him or the wheels of industry, which he alone turned, would halt and wealth for no one would be available...

During this period I was constantly preoccupied with the analysis of every film, which I saw, and in considering whether I could make them here. There was no doubt whatsoever about the utility of the profession and its importance as an industry...this was the period of the Swadeshi movement and there was profuse talking and lecturing on the subject. For me personally, this led to the resignation of my comfortable government job and taking to an independent profession. I took this opportunity to explain my ideas to my friends and leaders of the Swadeshi movement. Even people who were familiar with me for 15 years found my ideas impracticable.

Our best corporate citizens are also our most creative... Sixty years ago, when the Russians beat us into space, we didn't deny Sputnik was up there. We didn't argue about the science, or shrink our research and development budget. We built a space program almost overnight, and twelve years later, we were walking on the moon. That spirit of discovery is in our DNA. We're Thomas Edison and the Wright Brothers and George Washington Carver. We're Grace Hopper and Katherine Johnson and Sally Ride. We're every immigrant and entrepreneur from Boston to Austin to Silicon Valley racing to shape a better world. And over the past seven years, we've nurtured that spirit.

Our time is Gothic in its spirit. Unlike the Renaissance, it is not dominated by a few outstanding personalities. The twentieth century has established the democracy of the intellect. In the republic of art and science, there are many men who take an equally important part in the intellectual movements of our age. It is the epoch rather than the individual that is important. There is no one dominant personality like Galileo or Newton. Even in the nineteenth century, there were still a few giants who outtopped all others. Today the general level is much higher than ever before in the history of the world, but there are few men whose stature immediately sets them apart from all others.

But as far as our own world is concerned, its gradual leveling-down - or, we might say, its death - appears to be proved. And how will this process affect the fate of our spirit? Will it wane with the degradation of the energy of our world and return to unconsciousness, or will it grow according as the utilizable energy diminishes and by virtue of the very efforts that it makes to retard this degradation and to dominate Nature? - for this it is that constitutes the life of the spirit. May it be that consciousness and its extended support are two powers in contraposition, the one growing at the expense of the other?
